Nebius Group shares fall 5.12% after-hours amid broader selloff in AI infrastructure equities.

Nebius Group (NBIS) fell 5.12% in after-hours trading, driven by a combination of bearish factors ahead of its scheduled fourth-quarter earnings report on February 12, 2026. Recent news highlighted institutional selling, including WCM Investment Management LLC reducing its stake and SBI Securities upgrading its rating amid valuation concerns post-rebrand. Analyst reports from Seeking Alpha and MarketBeat also noted overcorrection and volatility linked to uncertain AI infrastructure demand. The stock’s decline aligns with broader selloffs in AI-related equities and mixed institutional sentiment, as investors appear to price in potential earnings misses or valuation challenges ahead of the February 12 release.
